No. 849,597. Specification of Application tiled March '31,

a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have. invented certain I new and useful Improvements in (ompressor- Valves, of which the following is a specilicatitm,;relerencc heing had to the accompanying drawings, forming a part thereof.

This invention relates particularly to compressors which have automatic YttiYPS actu- 'ated by changes in pressure and are designed .to operate on air or elastic lluids and in whici it is desirable to reduce the clearance v space as much as possible. particnlnrlv when high pressures are to he produced and 11min its mam ohjects are to reduce the clearance-space, to make the. suction and mined.

discharge valves interchangmtldc, thus preventing increase of the clearerice-space if the ,valves are accidentally misplaced and avoiding the necessity of making and keeping on hand two kinds of valves, and generally to improve the construction and operation of com ressors of this class.

T e invention consists in certain novel features of construction and in the peculiar arran emcnt of parts hereinafter particularlyilcscrihed, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in both l'igures.

Figure l is a vertical section of one head of a compressor to which my improved valves are a )plied in e. plcnc indicated hy the line- 1 1, lg. 2, perpendicular to the axis of the cylinder and cutting the suction and dis- 0. iarge valve chambem lengthwise and centrally; and Fig. 2 is a. vertical longitudinal section in a plane indicated by the line 2 2, Fig. 1, cutting the suctionwalve chamber lengthwise and centrally.

a and b designate the suction and discharge valve chambers, which in the present case are shown as formed side by side in a need 0 of. a compressor-cylinder. They are open at their upper ends, and at their lower ends valve-sats are formed or provided around ports, one of which on the suction side commun cates with the air inlet or supply assage (I and the other on the discharge side with a. port c, opening directlvinlo the con ressor-cylinder. Above the valve-sent on t io suction side the valve-chamher u communicates through a portj'directly with the compressorcylinder, and ahove the. valveseat on'the discharge side the chamber l) Letters Patent.

The valve-elmmhers are closed at their upper ends h v caps or covers it, holted or otherwise secured thereto and formed or provided with plugs i, which exltend dmvnvvardlv into and lill the valveehnmhcrs to within a short distance of the valve-seats at their lower ends.

The plugs i are formed witlricentral vertical sockets j. in which the stems lc-of the. suc tion and discharge vulves I are titted and guided. 'lhesc valves are of the disk or puppet t vpe and are prel'erahlv lormed h'clow their heveled Working laces with guidingvvings. as shown. The lower ends of the plugs 'i. which constitute stops for limiting the lilt or upward movement of the valves, are prcl'erahly provided with grooves In to )rcvent the valves from sticking thereto. lhc plug 1', nenrly lilling the suction-valve chamher a, which is in constant. communication with the compressorwylinder, reduces the clearance-space of the compressor just enough hptttt heing lelt between the ower end of the pin and the valve-scat to allow for the required lift or opening of the. suctionvalve. The sockets formed in the plu s 'i, all'ord long guiding-hearings for the va vestems and serve to hold the valves securely in the proper relation to their seats. The valves, as well as the covers and plugs, with their guiding-sockets, are made exnctlv alike so that if they are accidentally interchange or misplaced the t'lQtlIfllKU-SPQCQ will not be increased and the operation oi the com pressor will not he nllccted.

' lclmm- 1. In a compressor, the combination of a helow a valve-scat, and with a port above the valve-seat for constantcommunicntion with and in crosssection lillin the valve-chamber within a short distance ol the valve-seatyand a suction-valve provided with a stem which is titted and uided in said plug, substantially as dcscri led.

2. in a compressor the c'omhination of a. disclmrge-valve (llltllllllfll formed with a port hclow a valve-seat to open into a compressorcylinder and at discharge -ipassn eleading from the. chamber above tic va ve-seat a plu [n'ojectiug into and in cross-section tilla compressoncylindcr, a plug projecting into Various changes in minor details of construction may he made within the principle suction-valve chamber formed with an inlet sewer? and interchangeable suction and discharge valves having stems fitted and guided in the sockets of said plugs, substantially as de scribed.
